{"product_id":"holley-121-5-accelerator-pump-discharge-nozzle-check-needle","title":"Holley 121-5 Accelerator Pump Discharge Nozzle Check Needle","description":"A good selection of accelerator pump discharge nozzle sizes is indispensable to the proper tuning of the accelerator pump system.  The nozzle hole size determines the rate of fuel discharge.  A larger hole will shoot the fuel at a faster rate, and with less pressure, than a smaller hole.  Sizes are stamped on each nozzle.  For example, the number 31 indicates that the nozzle hole size is .031-inches.  Various styles of nozzles are offered by Holley.\u003cbr\u003e\u003cbr\u003e\u003ch5\u003eSpecifications:\u003c\/h5\u003e\u003cbr\u003e\u003ctable class=\"descr-table\" border=\"0\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_ASC\u003c\/td\u003e\n\u003ctd\u003eHolley Performance Emission Code 5: This part is legal for sale or use on Emissions Controlled Vehicles; Uncontrolled (Non-Emissions Controlled) Vehicles; and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_ASM\u003c\/td\u003e\n\u003ctd\u003eReplacement pump discharge needles for all Holley 4150; 4160; and 4500 series carburetors.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DEF\u003c\/td\u003e\n\u003ctd\u003eCarburetor Accelerator Pump Nozzle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DES\u003c\/td\u003e\n\u003ctd\u003eAccelerator Pump Discharge Nozzle Check Needle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_EXT\u003c\/td\u003e\n\u003ctd\u003eAccelerator Pump Discharge Nozzle Check Needle; Replacement; For Holley 4150\/4160\/4500 Series Carburetors;\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_FAB\u003c\/td\u003e\n\u003ctd\u003eIncludes 2 Gaskets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_FAB\u003c\/td\u003e\n\u003ctd\u003eReplacement Part\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_INV\u003c\/td\u003e\n\u003ctd\u003eACCELLERATOR DISCHG CHECK NEEDLE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_MKT\u003c\/td\u003e\n\u003ctd\u003eA good selection of accelerator pump discharge nozzle sizes is indispensable to the proper tuning of the accelerator pump system.
